Multiple league sources have told PFT that, for the most part, the negotiating process has proceeded slowly and tentatively. In most cases, teams are still expressing interest and discussing contracts in terms of general concepts, without many hard, specific offers being made. It’s creating a desire in many reaches of the league to move from negotiation to consummation.
